Abstract
PURPOSE: To promote a miniaturization simultaneously with a static torque enlarged and a productivity enhanced, by providing the poles, numbering a/2 in one unit and a/4 in another, as the fixed pole energized in either of polarities, with respect to a number of magnetized poles a of the rotor.
CONSTITUTION: In case of a synchronous motor of inductor type with a permanent magnet, for instance, magnetized in eight poles, provided as the rotor, in a lower pole part 1 of pole units 1, 2, energized by a coil 3, lower pole pieces 1A, numbering 1/2 of the number of magnetized poles in the rotor 4A, that is, numbering 4, are formed as the fixed pole, and in an upper pole part 2, upper pole pieces 2A, numbering 1/4 of the number of the above described poles in the rotor, that is, numbering 2, are formed similarly as the fixed pole. When applied a voltage to the coil 3, if energized the lower pole piece 1A in N polarity and the upper pole piece 2A in S polarity, poles of the rotor 4A, N1, to N4, S1, S3 will be in a state of repulsion with corresponding stator poles facing to each other, causing the rotor 4A to rotate in a direction of P
